What we measure
In the oil, viscosity, water and moisture, oil ageing, particle contamination (ISO 4406 code) and the wear-metal trend are measured. On the machine, vibration level and temperature are monitored. When a reading moves away from the machine's normal range, the screen changes from green to amber or red. Warning signs and what they mean
What we do not measure: metal identification (which metal a particle is), acid and base number (TAN/TBN) and vibration spectrum analysis (FFT). These tests need a laboratory and a specialist. DataMonitor does not replace them. It works alongside them. The system watches for warning signs and gives early warning. It does not diagnose faults.
Automotive suppliers FAQ
How often should press hydraulic oil be checked?
With fixed online monitoring the oil is measured continuously, so frequency is no longer an issue. With a portable analyzer, the right interval depends on three things. These are how critical the press is, the manufacturer's recommendation and the trend of earlier readings. Once a value starts to change, it makes sense to measure more often.
Can oil condition be monitored without stopping the line?
Yes. Once the sensor is installed, it measures in the oil line while the machine runs. You do not need to stop the line to take a sample. The readings appear on the monitoring screen, and an alarm sounds when a limit is crossed. A local server lets you watch all your presses on one screen.
How should I read an ISO VG 46 viscosity measurement?
An ISO VG grade gives the viscosity of the oil at 40 °C. So VG 46 means about 46 cSt within a ±10% band (US USBR FIST 2-4). An in-line reading depends on the oil temperature at that moment. The number on the screen may therefore not match the 46 on the label. What matters is how far the value drifts from the normal level of your own machine over time.
